The present invention relates to a process for the one-pot hydrogenation and dehydration or isomerization of an organic compound, and to a catalyst composition for this process comprising transition metal particles having particle size below 50 nm supported on a material comprising at least one fluorinated polymer (P), wherein polymer (P) bears &#x2014;SOX functional groups, X being selected from X' and OM, X&#x2032; being selected from the groups consisting of F, Cl, Br and I; and M being selected from the group consisting of H, and alkaline metal and NH.

One-pot process using heterogeneous catalyst

Catalytic materials, particularly membranes, exhibiting high activity, high stability and low metal leaching in a variety of chemical reactions, particularly selective hydrogenations of unsaturated organic compounds, are described. These membranes are inorganic/polymeric hybrid materials in which metal complex molecular catalysts are immobilized or metal nano-particle catalysts are embedded. More specifically, the catalytic materials of the present invention exhibit higher activity and selectivity, and can be used in more extensive kinds of organic solvents than the conventional hybrid catalytic materials due to improvement in the affinity to organic solvents by containing the specific polymeric additives.

Inorganic/polymeric hybrid catalytic materials with high activity in various solvents

Catalytic materials with high activity in various chemical reactions as well as high durability are described. The catalytic materials are composed of specific, hybrid combinations of inorganic/polymeric compounds containing metal nano-particles therein, and can be easily reused with negligible catalysts leaching. They are particularly useful, but not limited to, the hydrogenation of substituted &#x3b1;,&#x3b2; unsaturated acids or esters.
